ANNUNCIATOR.

Specification of Letters Patent.

Patented Aug. 27, 1907.

Application filed November 14:, 1904:. Serial No. 232,590.

To all whom it may concern:

Be it known that I, Fnnmuc SIDLER, a citizen of the United States, and a resident of West Pullman, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Annunciators.

The object of my invention is to provide an annunciator adapted to be used by barbers and others in enabling the operator to announce by means of an audible alarm and an indicator, that a subsequent customer is in line to be waited upon, the indicator disclosing what party is next, as I use in conjunction with my invention a plurality of tokens, each provided with a number or other identification symbol, so that when the annunciator index points to a certain number, the party holding that number will be next to receive attention.

In the accompanying drawings, I have shown in Figure 1 a rear view of an annunciatorembodying my invention. closing the method of securing the index carrying shaft to the ratchet wheel, as used in my invention. Fig. 3

shows a broken detached detail of the block supporting the pendent swinging armature, used in actuating the ratchet wheel. Fig. 4 discloses a top view of the swinging armature and connected pawl, while Fig. 5 shows a face view of my index.

'In carrying out the aim of my invention, I employ a suitable base-board as shown at A, which is provided with theornamental molding B in front and upon the rear, with the projecting boards 6-6 and 77, forming a box or housing, which may be covered by means of a suitable back, adapted to be fastened to the slats a vertically positioned adjacent the box or housing forming members 7 and 7, these slats not extending out as far as the members 77.

Secured to the front portion of the base-board A is the dial M provided with a set of numbers in regular series. In the drawing I used 24 such numbers upon the dial M. Depending from a set of pins b are the tokens 0, there being one token for each number appearing upon the dial, and these tokens c are hung upon a pin within the frame B opposite the corresponding number upon the dial.

Held within the supporting bar D, and passing through base A is the index carrying shaft G, the supporting bar being held by means of the blocks d d, as shown in Fig. 1. In front, this shaft G is provided with the index L, and loosely held upon this shaft G is the ratchet wheel F. In Fig. 2 a detail is shown of this shaft and ratchet wheel, and in Fig. 1 a rear elevation is shown. Extending from the ratchet wheel F is an arm F which passes through the opening within the shaft G as is shown in Fig. 2, so that the ratchet wheel F is secured to the shaft G by means of this arm F, which is preferably of wire.

Secured to the pin 17, as shown in Fig. 1, is a pawl 18,

which pawl works in conjunction with the ratchet Fig. 2 shows a broken detached detail diswheel F, and operates as a stop pawl the movement of this pawl 18 being regulated and stopped by means of the pin 16.

Secured to the base board A is the block K, an edge pin M, pivotally supporting the pendent swinging armature J, as shown also in Fig. 1, this armature below being provided with the downwardly projecting head J, so that the armature is in the form of an L approximately. Loosely working within this lower end of head J, by means of the end 1 is the pawl E, the hooked end a of which loops over the ratchet wheel F, as is shown clearly in Fig. 1.

Passing through the block d is the stop arm H against the upper recurved end P of which the pawl E strikes, to form an electric circuit with said stop arm H, when said pawl is carried upward.

Held adjacent the pendent armature is the electric coil O, the lower projecting end 16 of which, when it be comes magnetized attracts and carries forward the lower end of the armature J, this coil G being held by means of the blocks 14 and 15, and being wound by means of a suitable wire coil the ends a and 19 being prolonged to form an electric circuit, the conductor a being carried to the terminal 30 of the battery B, the conductor 19 by means of the connection 10 being led to the alarm K, as shown in Fig. 1. I

In Fig. 3 I have shown the conductor a as secured'to the pendent swinging armature J as this armature forms one terminal of the conductor a. The stop arm H, by means of the conductor 12, is led to the remaining pole of the alarm K, as shown in Fig. 1.

The battery B is in circuit with the batteries A, A and B, as shown in Fig. 1. The conductor 8 extends from battery A to the terminal 4 from which extends the conductor 3 leading to the push button 1, from which push button extends the conductor 2 leading to the terminal 5, this terminal by means of the conductor 9 bcing'connected to the conductor l9 extending from the coil 0.

Now I have two circuits in my invention, the first comprising the conductor a extending from the battery 13 the conductors a, 19, 9, 2, 3, 8,24, 25, and 30 also at tached to the battery B. The shunt circuit comprises the conductors a, J, E, H, 12, 12, and 10, connected to the conductor 19. as shown in Fig. 1. The battery B is provided with the binding posts 30 and 29 and the battery B is provided with the binding posts 27 and 28. The conductor 30 extends from the post 29 to the post 28 while the conductor 25 extends from the post 27 tothe post 23 of the battery A which is provided with the second post-22. The battery A is provided with the posts 21 and 20, the conductor24 being secured to the posts 21 and 22 while the conductor 8 extends from the post 20.

In order to provide a holder for the batteries, I use a view being shown in Fig. 3, which is provided with the Now, when properly constructed, the operation of my device is as iollows:-Used in the barber shop, a customer will come in, and we will assume remove the token 2, We assuming that a customer is in the chair being shaved. As soon as the barber is through with the customer he presses the button 1, which would complete the first circuit mentioned, to magnetize the coil 0, to carry the pendent armature J forward, to actuate the ratchet wheel F, and carry the index L forward to the number 2. As soon as the pendent armature E came in contact with the terminal P, the bell K would be rung, so that after the mechanism has been advanced, the audible alarm is actuated to notify the customer that some other number is next. This arrangement is of particular importance, in that if the operating mechanism is not actuated, the bell cannot be rung, so that the barber using the instrument, as well as the customer will always know that when the alarm is actuated the mechanism has been actuated. It is oi course understood that any number of these push buttons could be used one being led to each barbers chair or dentists chair, as the case may be.

As it would be difficult to arrange the ratchetwheel F and its connected pawls so that the index L would point true to each numeralupon the face of the dial, I have used the wire connection in the form of the arm F, as shown in Fig. 2, so that I first allow the pawls E and 18 to ind proper seatings within the ratchet wheel, and then by means of pliers, bend the stem F to move the shaft G, to bring the index L squarely before and opposite the number. From this it will be seen that the index L is adj ustably secured to the ratchet wheel F. This is further of special advantage in that, should the index become slightly disarranged in transporting the instrument, the operator could easily bring the index in alinement with the numbers in bending the arm F These instruments are made of various sizes and of any suitable material. I have shown four batteries, but it is of course understood that a less number could be used. I have further made the ratchet wheel F star shaped so I that the index can be shoved freely in one direction, so

that the index may always be brought to any desired number.

In referring to Fig. 1, it will be noticed that the head J is of suiiicient weight to swing the armature .1 out of a perpendicular, so that as soon as the current is released this armature will gravitate backward to carry the pawl' E off of one tooth into engagement with the next tooth.

In connection with the ornamental frame B suitable advertising signs may be used if desired. And

Having thus described my said invention, what 1 claim as new and desire to secure by United States Letters'Patent is:

The combination with a suitable supporting base, of a shaft revolubly held by said base, a ratchet wheel loosely working upon said shaft, an arm extending from said shaft and secured to said ratchet wheel, an index secured to said shaft, a stop pawl engaging-said ratchet wheel, an electro magnet, a pendant armature adjacent said electro magnet, a pawl extending from said armature and in engagement with said ratchet wheel, an electric circuit in connection with said electro magnet, and a bell circuit adapted to be closed by the movement of said armature substantially as set forth.

In tetstimony whereof I aifix my signature in presence of two witnesses.
